To all whom it may concern:

Be it known that I, JOHN H. HALFoRD, a citizen of the United States, residing at Bridgeport, in the county of Montgomery and'State of Pennsylvania, have invented or discovered certain new and useful Im rovements in the Art of Treating Worsted am, of which the following is a specification.

This invention relates to the art of treating worsted yarn, and it has for its object the production of merchantable packages of such yarn which will be in the most desirable condition for use.

In carrying the invention into effect, the worsted yarn, after having been finished by being dyed, bleached, or scoured, is wound into balls (which will preferably be hollow) by any suitable winding machine or apparatus, and is then subjected to a steaming process, whereby the balls are thoroughly steamed, in any suitable manner.

somewhat stretched, and its loftiness, or flufliness, and elasticity are thereby impaired. The steaming of the balls restores, or increases, the loftiness and elasticity of the yarn, and hence places the yarn in a condition, equal, or superior, to the condition it was in before winding.

\ Having thus described my invention, I claim and desire to secure by Letters Patent:

1. The herein-described method of treating finished worsted yarn, consisting in winding the same into balls, and then steaming said balls.

2. The herein-described method of treating finished worsted yarn, consisting in winding the same into hollow balls, and then steaming the balls.

In testimony whereof I aflix my signature.
